I tried to copy this soup from Campagne. It ended up being a combination of 2 different recipes. Here goes:
1 lb carrots, chopped and peeled; 1/2 onion, sauteed with garlic
1/4th teaspoon cumin, herbs de provence, salt and pepper
Simmer for 20-30 minutes. Puree in blender.
Mix in a small amount of whipping cream.
